tests: Test IPv6 and ppc64 in the PXE tester

The firmware of the pseries machine, SLOF, is able to load files via
IPv6 networking, too. So to test both, network bootloading on ppc64
and IPv6 (via Slirp) , let's add some PXE tests for this environment,
too. Since we can not use the normal x86 boot sector for network boot
loading, we use a simple Forth script on ppc64 instead.
